IMPROVEMENT I ll GITE-CEUSHERS.A

'I ALL WHOM I'l MAY CONCERN:

Be it known that we, BENNET I-IOTCHKISS and SAMUEL C. G-OODSELL, of NewHaven, in the `county of New Haven, and Stato of Connecticut, haveinvented new and useful improvements in Machines for Pulverizing Quartz;and we do hereby declare the following, when taken in connection withthe accompanyingdrawingslnd the letters of' reference marked thereon, tobe a full, clear, and exact description of the same;` and which said ldrawings constitute part of this specification, and represent, in

Figure L1, a front view.

Figure 2, 'a side view,

Figure 3, a top view.

Figurel 4, a vertical central section. v

Our invention v'relates to an improvement in machines for pulveriaiugquartz and'othei ores; and consists, first', in'a mechanism forconvertingrotary intoreciproeating motion; second, in thc constructionof th'ebcx which contains and the hammer whichpulverizes the quartz, andtube communicating therewith, so as 'to automatically feed the lumps tobe vp ulvcrized and discharge the same when pulverizcd.

To enable others skilled in the artto constructaud use our improvement,we .will'proceed to 'fully describe the same as illustrated intheaccompanying drawings. I y

p A is the bed, B a frame which supports the hammer C and its operativemechanism, and is adjustably vfixed to th'e bed 4A. l.The 4hammer C isfixed toa bar, D, which moves freely up and down in guides'E; F is thedrivingshaft snpported'on the frame B, and so as to'revolve freely inbearings` G.' Thesai'd shaft between its two bearings G Gr'is formedinto two cranks I I', (see-iig. 3,) each of which is eonnect-edto thebarD of the hammer by flexible cords or straps, L and L', whichpass between,pulleys N and N; .the cord L passing down is secured to the bar D at'the other cord passing up and secured to the bar D at b, as seen in iig.4. Ois a cast-iron box setintoithe bed- A, as seen in iig. 4, restingupon an elastic substanceorspring I, or its equivalent. Within the saidbox O I place the hammering block R, and'insert through the said box,as'seen in figs. I and 2, two tubes, S and T; the tube T being used tointroduce the pieces or lumps of quartz to be crushed, and the tube S toconduct thepulvcrizedquartz from4 the box as hereafter described. Thehammer Cl should nearly lill the box O by piston rings o rA otherwise,as seen in iig. 4, so that as. it descends it'will force air int-o .thebox to create a blast suhcient toblow the powdered quartz out throughthe tube S, anchas tlchammer rises other pieces er lumps will enterthrough thc tube Tbeneath the hammer on to the block Rto be pulverized.Tlietubc S should be made 'the proper length in proportion to the blastcreated by the'desccntof tl'1c.liammer, aud is set perpendicular, itstop turned outward or not as requi1'ed,so.tliat the heavier or' notfully pulverilzed particles will fall back into the box, while thatwhich issuicientl'y pulverized will pass out with the air. When thedriving-shaft is-made to revolve from the position'denoted in iig.' 4the cranks I will cause the hammer C to rise until the crank I hasattained thc position opposite the circle which -it describes, orrelatively, as that of the crank I, while th'ecrank I will advancetowards the hammer to allow the hammerto draw up the strap L connectedthereto, Auntil the said crank I has attainedthe relativeV position ofthe crank I.` At this pointlthe hammer is raised tdthe position denotedin red, g.' 1ilhe cranlrs continuing their revolution, thc crank I willdraw the hammer down while the crankI will in its turn release its powerupon the hammer to permit its descent and when rapidly revolving. Thepower thus added to the hammer in its descent is in proportion as thevelocity ofthe crank is greater than the natural gravity' of the'hammer. As by this construct-ion the desccntet the hammeris toapositive'point, it is necessary that some adjustment should beintroduced tao-provide for the variation in the size of the lumps4inserted beneath the' humilier. Asthe lumps may to `a certain extentbc'regulated before their introduction, a'slight adjustment only isneeded for thispurpose. I introduce an clasticsubstanceor spring Pbeneath the box O; this may-be ofvsteel springs, rubber, or anyequivalent therefor which willallow thc box O to be slightly depressedand cause it again toresumeits natural position. 'This arrangement willfully compensate for the slight variation which .may exist in the lumpsas prepared forY the pulverizing. Another adjustmentisrequiredto allowthe insertion of lumps of a larger size. is designed' that the lumpsshall be graded so that at one time the lumps of nearly the same .sizemay be placed in the boxI and another time lumps of anothernearlyreglilar size.) For this purpose a screw, W, is inserted throughthe'f'rame B into lthe bed A', which by being turned, (here representedas turned by means of a worm, will raisc'or lower the frarue ns'the casemay be, andthe frame secured to the bed bymeans ofV the-bolt Y. Thisarrangement is fully shown in'fig'. 4.4 I t now remains to describe theclutch' by* which we connect or disconnect the power which. drives themachine. On the shaft F I tix a plate,- das seen in hg. 3,on the saidshaft, and beside the said plate ZI place a driving-pulley, so as torevolve freely thereon.' I form thevsidc of the-pulley neXt to theplated to correspond to the form' of the said plate, be it dat, conical,concave, pr comeny preferring a conical form as seen in'ig. 3. Power isapplied to theV pulleyfin the usual manner. By pressing the saidpulleyfrmly against the l plate d, the pulley revolving so that thefriction' between the two will' 'cause the plato and the 4shaft to whichit is attached to revolve with it, by releasing the pressure upon thesaid pulley. the potver will befdisconnectedand the operation of thehammer be arrested at the completion of each revolution. -My arrangementfor4 pressing the pulley against the plate as seen in gs. 1, 2, and 3: eis a spring, one end4 of which bears upon the hub of the' pulley as seenin fig'. the other end secured to some part of the machine. Frouisaidspring e a cord or its equitalent li is attachedto the .treadle m,'so that by placing the foot upon `the treadl'efm the spring will beborne against the pulley, .pressing it against the plate d'withsuiicient force to cause it to' revolve as before described. yRemovingthe foot from the treadle the power will bedisconnected. By'varying thepressure upon the pulley so as to lessen o 'r'increase the friction, thevelocity of the driving-shaft may be increased or decreased at thepleasure of .theoperatoiu` We do not wish to be understood as confiningourselves to this particular description of c1utclror"pulley',as in.many casesa common pulleyrnay be fixed' to the driving-shaft to impart aconstantrnotion to-the hammer. This is desirable after the quartz hasbeenr broken, that is,"\rlic'n p ulveriiing, or, if preferred, and in'many cases it would be desirable, thatboth a fixed pulley and the clutchpulley'should be appliedi`n which case a loose `pulley should alsobeattached in suchrelation-to theixed pulley that the band' may be shippedfrom one tb thc' other as required, in such manner as 'any personskilled in' the use of-machincrywill readily understand.' i

We have entitled our invention. a machine for pulverizing'quartz, andhavedescribed it asfor that purpase7 but we do not wish to .beunderstood as limiting our invention to suchpurpose, as the mechanismwhich we describe for operatingthe hammer. inay'be used for operating`hammers for various purposes.

W'e do not broadly claim -an outletand inlet tube in pulverizingmachines. y p

v Having therefore thus fully described our invention, what WeV claiinnew and usefulfanddesire Vto secure by Letters Patent, is I i i 1. Theshaft F with doublecranks IVI, straps L and L', hammer C, begr O, whenconstructed and arrangedv lto operate together substantially asdescribed.
